CONTINUE WITH LIGHT SOUTHERLY FLOW OFF THE GULF PERSISTING ON THE
BACKSIDE OF THE RIDGE OVER THE EASTERN GULFMEX AND SOUTHEAST
ATLANTIC COASTAL STATES.  WILL MAINTAIN MENTION OF FOG AGAIN
TONIGHT...WITH AREAS OF DENSE FOG EXPECTED MOST ANYWHERE.  CURRENTLY
NOTING A DECK OF LOW CLOUDS AND LIGHT FOG JUST OFFSHORE AND
LINGERING ALONG THE COAST BETWEEN FORT MORGAN AND DESTIN.  THAT

OVERALL...PERSISTENCE CONTINUES TO BE A PRETTY GOOD FORECAST NEXT 24

.LONG TERM (WEDNESDAY THROUGH NEXT MONDAY)...WE KEEP THE LIGHT TO
MODERATE SOUTHERLY FLOW GOING THROUGH MIDWEEK.  THE NEXT KEY FEATURE
TO WATCH WILL BE THE SHORTWAVE FORECAST TO EJECT EAST OUT OF TEXAS

STATES A SHOVE SOUTHEAST THURSDAY INTO FRIDAY.  WE CONTINUE WITH A
SIMILAR FORECAST (IN COMPARISON TO PREVIOUS PACKAGES) THIS RUN WITH
CHANCE POPS COMING BACK INTO THE PICTURE THURSDAY INTO FRIDAY AS THE
FRONT MOVES GRADUALLY ACROSS OUR AREA.  LEFT SOME LINGERING POPS FOR
(MOSTLY RAIN WITH MAYBE A FEW ISOLATED ELEVATED THUNDERSTORMS)
SATURDAY GIVEN POTENTIAL FOR ISENTROPIC LIFT NORTH OF THE FRONT (BY
THEN JUST OFFSHORE) AS A SECOND SHORTWAVE EJECT EAST OUT OF THE
SOUTHERN PLAINS.  /05

&&

.MARINE...HIGH PRESSURE WILL REMAIN CENTERED OFF THE SOUTHEAST
ATLANTIC COAST THROUGH WEDNESDAY. THIS WILL CONTINUE TO CREATE A
LIGHT TO OCCASIONALLY MODERATE EAST TO SOUTHEAST WIND FLOW OVER THE
ALABAMA AND FLORIDA GULF COASTAL WATERS. DENSE FOG WILL AGAIN BE A
THREAT TONIGHT AND TUESDAY NIGHT AS A SOUTHEASTERLY FLOW TRANSPORTS
A WARM...MOIST AIRMASS OVER THE COOLER NEAR SHORE WATERS. HIGH
PRESSURE WILL WEAKEN AND SHIFT EASTWARD AS A COLD FRONT APPROACHES
FROM THE NORTHWEST THURSDAY NIGHT. A STRONG NORTHERLY FLOW WILL
FOLLOW IN THE WAKE OF THE FRONT ON FRIDAY. /13

&&

WEDNESDAY...WITH AFTERNOON RELATIVE HUMIDITY VALUES FALLING INTO THE
35 TO 40 PERCENT RANGE OVER INLAND PARTS OF SOUTH-CENTRAL ALABAMA
AND OKALOOSA AND WALTON COUNTIES DURING THE AFTERNOON.
OVERNIGHT...ENOUGH HUMIDITY WILL BE IN PLACE WHEN COMBINED WITH THE
ONSHORE FLOW FOR LOW CLOUDS AND FOG TO FORM. THIS FOG WILL BE DENSE
